A cylinder contains 640 gm of liquid oxygen. The volume occupied (in litres) by the oxygen, when it is released and brought to standard conditions (0°C, 760 mm Hg) will be __________ litres.
A. 448
B. 224
C. 22.4
D. Data insufficient; can't be computed
Answer: Option A
Solution (By Examveda Team)
Since, every fluid at $$S.T.P$$ occupies $$22.4\,\,ltrs$$ of volume per unit mole.Here given number of moles $$ = \frac{{{\text{weight}}}}{{{\text{gram molecular weight}}}} = 20$$
So, the volume occupied $$ = 22.4 * 20 = 448\,\,ltrs.$$
